Blair Witch is a 2016 American found footage supernatural psychological horror film directed by Adam Wingard and written by Simon Barrett. It is the third film in the Blair Witch series and a direct sequel to The Blair Witch Project (1999), which ignores the events of Book of Shadows: Blair Witch 2 (2000). It stars James Allen McCune, Callie Hernandez, Brandon Scott, Corbin Reid, Wes Robinson, and Valorie Curry. The film follows a group of college students and their local guides who venture into the Black Hills Forest in Maryland to uncover the mysteries surrounding the disappearance years ago of Heather Donahue, the sister of one of the characters. Initially, the film's connection to the Blair Witch franchise was kept secret, with the film having been shot under the fake title, The Woods.

It screened at San Diego Comic-Con on July 22, 2016 and premiered at the 2016 Toronto International Film Festival on September 11, before being theatrically released in the United States on September 16 by Lionsgate. It received generally mixed reviews from critics. Despite grossing $45 million on a budget of $5 million, the film was considered a box office disappointment.
